Randy Jackson quickly explains that theme weeks are there for … well, I’m not sure if he really did explain it too well. Basically, he thinks the “music of yesteryear” is better.

Does that include Kansas and Chicago tunes? Mmm-kay.

Group sing-along time. A few quick thoughts:

Michael Johns seems back on tonight and gains a few points. David Cook is wearing a mini-tuxedo T-shirt — and loses a lot of points.

Kristy Lee Cook is boring even after one verse. Carly Smithson is so much better than most of the girls it’s embarrassing. Amanda Overmyer is continuing last night’s trainwreck vocal path. But at least she toned down the hair.

Ramiele Malubay needs to pull her pants down from under her arms.

Jason Yeager. Why?

Boy, this is a long medley. And awkward. It’s over — and not a moment too soon.

The guys, as last week, are up first. A quick recap. David Cook feels bad about sassing Simon Cowell. Too little, too late.

And, honestly, I still don’t see the wow over David Hernandez. I can already see the comments coming. Bring it!

Dim the lights! Michael Johns, Chikezie and Jason Castro are safe.

It’s down to Jason Yeager and a stricken Danny Noriega. And — thank you! — Yeager and his blonde streak are sent back to Grand Prairie.

“You need a heck of a lot of experience,” Simon says. “You don’t stand out in the crowd at the moment. You’re not a bad singer.”

His final performance says otherwise. Glad we won’t have to hear that again.

Recapping the girls, with a bonus snap from Amanda: “I’m not asking them to buy an album.”
